  • Page 25: Stop / Fuel Solenoid Selection

    5.1.6 Stop / Fuel Solenoid Selection (P16) This parameter allows the use of either a Stop solenoid or a Fuel solenoid. (See Section 5.1.10 Engine Starting.) If Fuel Solenoid selected, the fuel solenoid will be energised while the engine is running and de- energised to cut off the fuel and stop the engine.
